Insta-carry adders are fast and compact, making them a great choice for your ALUs, CPUs, mini-games or whatever you can think up. In this tutorial I explain what an insta-carry adder is, why they're so efficient, and how to build one. If you have any questions feel free to ask in the comments section!

Padraic Edgington

This video follows on from previous videos about truth tables and Karnaugh maps. It hints at how truth tables and K-maps can be used in circuit design. It covers some well known logic gate combinations including NAND, NOT and XOR, and how logic gates can be combined to make a half adder, then a full adder and ultimately a ripple carry adder capable of multi-bit binary addition.

In this video I will look at the problems that can arise in unsigned and signed systems with overflow and underflow, which is where our system goes beyond its physical limitations. I will look at how you can detect that overflow is occurring in a digital system and how you can design a logic circuit to detect its occurrence. The video then describes underflow and finally, presents a few interesting questions with solutions.

GATE 2017 CS Question Paper Complete Solution
Q 9. When two 8-bit numbers A7....A0 and B7.....B0 in 2’s complement representation (with A0 and B0 as the least significant bits ) are added using a ripple-carry adder, the sum bits obtained are S7….S0 and the carry bits are C7….C0. An overflow is said to have occurred if
(a) the carry bit C7 is 1
(b) all the carry bits (C7….C0) are 1
(c) (A7B7 .(𝑆7) ̅ + (𝐴7) ̅ . (𝐵7) ̅ .S7 ) is 1
(d) (A0 .B0 . (𝑆0) ̅ + (𝐴0) ̅. (𝐵0) ̅. S0) is 1

Binary addition in two’s complement form with overflow detection. Just because a carry out is 1 does not mean that there was an overflow. For the last bits for two numbers xor carry in with carry out to determine overflow.

This video is an introduction into 4-bit Binary Addition. It discusses the concept of binary addition and extends on a previous video that demonstrates how to create a half adder and full adder. It shows how to cascade full adders together to create the 4-bit adder circuit and discusses the use of the 74HC283 4-bit full adder with fast carry. This video is part of an introductory module on Digital Electronics that takes place at Dublin City University (DCU), Ireland. See: www.eeng.dcu.ie/~molloyd/EE223/

For large adders the complexity of the carry-lookahead circuitry increases rapidly. In this case smaller carry-lookahead adder blocks can be combined in a hierarchical fashion to obtain a tradeoff between speed and complexity.

This is the 3rd and part in my Logisim Tutorial on designing a 3-Bit ALU. In the first part, we designed and implemented the the Carry-lookahead adder (CLA). In the second part, we implemented the 3-Bit AND, OR, and NOT functions. In this final part, we use all of the circuits we have designed in the first two parts, and actually wire up the 3bit ALU.
This is a 3 Part Series:
1) Design the CLA & Carrys, and the Implement the 3Bit CLA: http://youtu.be/7P3kzUju0fg
2) Design and Implement 3Bit AND, OR, and NOT functions: http://youtu.be/1k7xlVu8Z6s
3) Implement (Wire up) the ALU and doing some basic testing on it: http://youtu.be/knW4a14SJe8
